Sapphire Single-Point Level System Download printable brochure
Thermo Scientific Sapphire single-point level system performs well in aerated, attenuative, viscous, corrosive, and even more severe applications.
It combines a unique measurement technique with superior self-testing capabilities to ensure reliability and increase uptime. Based on time-gate technology, the system uses an advanced form of ultrasonic measurement to offer increased sensitivity. To guard against false alarms, the variable system qualification time accurately determines the presence of liquid in the measurement gap.Details:
